One of the most common questions business owners ask is: 

“How often do I need to test and tag my electrical equipment?”

The answer often surprises people. 

The law does not require every piece of electrical equipment to be tested and tagged every 12 months. Instead, it requires businesses to identify the risk, maintain electrical equipment in a safe condition, and determine an inspection and testing program that is appropriate for the workplace. 

Understanding this difference can save businesses money while ensuring they remain compliant and, most importantly, keep workers safe. 

The Legal Duty 

Under the Work Health and Safety (WHS) Act, a Person Conducting a Business or Undertaking (PCBU) has a duty to ensure, so far as is reasonably practicable, that workers are not exposed to electrical risks. 

The Code of Practice – Managing Electrical Risks in the Workplace explains that electrical equipment must be: 

• Maintained in a safe condition.
• Regularly inspected.
• Tested where necessary.
• Removed from service if found to be unsafe.

This means businesses must have a process to ensure electrical equipment remains safe throughout its life. 

Does Everything Need to Be Test and Tagged? 

No. 

Testing and tagging is only one control measure. 

Many businesses incorrectly assume that every electrical item must be connected to a Portable Appliance Tester (PAT) every year. In reality, some equipment may only require regular visual inspections, while other equipment in higher-risk environments requires routine electrical testing. 

The inspection and testing frequency should be based on: 

• The type of equipment.
• How often it is used.
• The environment it operates in.
• The likelihood of damage.
• The manufacturer’s recommendations.
• Previous inspection results.

What Should Be Checked? 

Every inspection should include a careful visual examination for signs of damage, including: 

• Damaged power cords.
• Broken plugs.
• Missing earth pins.
• Cracked casings.
• Loose fittings.
• Burn marks or overheating.
• Damaged extension leads.
• Exposed wiring.
• Evidence of water damage.

Many electrical faults can be identified through a visual inspection before specialised testing is even required. 

High-Risk Workplaces 

Some workplaces have a much greater risk of electrical damage than others. 

Examples include: 

• Construction sites.
• Manufacturing facilities.
• Warehouses.
• Workshops.
• Mining operations.
• Agricultural workplaces.
• Outdoor work environments.

Electrical equipment in these locations is often exposed to: 

• Moisture.
• Heat.
• Dust.
• Vibration.
• Impact.
• Chemicals.
• Frequent movement.

Because of these additional risks, inspection and testing usually needs to occur more frequently. 

Low-Risk Offices 

In contrast, equipment used in an office environment may be subject to very little physical damage. 

Desktop computers, monitors and printers that remain in one location may require only periodic visual inspections, unless there is evidence of damage or a higher level of risk. 

This demonstrates why a “one size fits all” testing schedule is rarely appropriate. 

Who Can Perform the Inspection? 

Visual inspections can often be carried out by a competent person who has been trained to recognise electrical defects. 

Electrical testing (commonly known as test and tag) should only be performed by a person who has the appropriate training, competency and suitable testing equipment. 

Workers should also be encouraged to inspect equipment before use and immediately report any defects. 

What Happens if Equipment is Damaged? 

Unsafe equipment should be: 

• Switched off where safe to do so.
• Removed from service immediately.
• Clearly labelled so it cannot be used.
• Reported to management.
• Repaired by a competent person or replaced.

Never continue using electrical equipment that shows signs of damage simply because it has a current test tag attached. A test tag is not a guarantee that equipment remains safe after it has been tested. 

Keeping Records 

Maintaining inspection records helps demonstrate that your business is actively managing electrical risks. 

Records may include: 

• Asset register.
• Inspection dates.
• Test results.
• Defects identified.
• Repairs undertaken.
• Equipment removed from service.
• Next inspection due date.

Good records provide valuable evidence if your business is audited or investigated following an incident. 

Practical Tips for Businesses 

An effective electrical equipment inspection program should include: 

• Maintaining an up-to-date electrical equipment register.
• Training workers to identify damaged equipment.
• Completing routine visual inspections.
• Scheduling testing based on the level of risk.
• Recording inspections and corrective actions.
• Promptly removing unsafe equipment from service.
• Regularly reviewing inspection frequencies based on workplace conditions.

Final Thoughts 

Testing and inspecting electrical equipment is about much more than attaching a tag to a power lead. It is about implementing a risk-based system that ensures electrical equipment remains safe throughout its service life. 

Businesses that understand the difference between visual inspections, electrical testing and ongoing maintenance are far better placed to protect their workers and demonstrate compliance with their WHS obligations. 

Remember, the question should not be “When do I need to test and tag?” 

Instead, ask: 

“How can I be confident that the electrical equipment my workers use today is safe?” 

That simple change in thinking is at the heart of effective electrical risk management.
